Invited for this month’s cover is the group of Prof. Frederic Guittard from Université Nice Sophia–Antipolis. The cover picture shows a superoleophobic stainless-steel mesh obtained by electrodeposition of fluorinated conducting polymers. Read the full text of the article at 10.1002/cplu.201300315

12The “Surfaces and Interfaces Group” is one part of the Laboratory of Condensed Matter Physics (LPMC), which is a joint research unit (UMR 7336) headed by Université Nice Sophia–Antipolis and the CNRS (France). The main activities of this group are the synthesis of organic and organic–inorganic hybrid materials to develop bioinspired materials and biobased chemistry. The research also encompasses fluorinated compounds and their derivatives. Our knowledge allows going from molecular concepts toward the construction of surfaces with specific properties that are then applied in different fields: NanoTech, SmartTech, BioTech. One major results concerns the preparation of superhydro—oleophobic—philic materials.

The main challenge is controlling the double scale of surface structures at the micro and nano levels. Finding solutions at the nano level is quite challenging with respect to building up biomimetic materials. The main aim is to match these organized materials and the surface chemistry to obtain stable superoleophobic behavior.

The main surprise was to discover how the polymer growth on stainless-steel meshes can highly affect the superoleophobic properties. The careful choice of the nature of the electrodeposited polymers at low or high deposition charges is also a key parameter to induce polymerization, especially around the mesh wires to form micro- and nanostructures while avoiding covering the holes. This publication highlights the ability to produce a specific microcoating with an internal nanostructuration required to reach superoleophobic properties.
